Subject: Flow API questions/Hierarchical Queuing feature support
Hi,
I have a question about Flow API.
test flow [add|del|enable|disable] [index <id>] "
"[src-ip <ip-addr/mask>] [dst-ip <ip-addr/mask>] "
"[ip6-src-ip <ip-addr/mask>] [ip6-dst-ip <ip-addr/mask>] "
"[src-port <port/mask>] [dst-port <port/mask>] "
"[proto <ip-proto>] "
"[gtpc teid <teid>] [gtpu teid <teid>] [vxlan <vni>] "
"[session id <session>] [spi <spi>]"
"[next-node <node>] [mark <id>] [buffer-advance <len>] "
"[redirect-to-queue <queue>] [drop] "
"[rss function <name>] [rss types <flow type>]",
It was mentioned that Flow action can be mark <id>. Is the mark-id is an
opaque field /meta buffer filed of the packet buffer. I am trying to see if
the is Mark id can be preserved until the packet is reached the output
interface . Does the Flow API expects support from hardware for flow
classification. Is the mark-id is stored in the meta-buffer field . Is
there any trace function or log where I can see this field set ?
Also, it looks Hierarchical Queuing support is not enabled in latest
release. Any plans to support it again in the future? I would to know
for an example coomand how to set the pktfield for heirarchial queing.
It's not clear for documentation how to set it based on packet fields like
src-ip, dst-ip, src-port, dst-port and proto. Do I need to mention mask
value for it ?
The command below is used to set the packet fields required for classifying
the incoming packet. As a result of classification process, packet field
information will be mapped to 5 tuples (subport, pipe, traffic class, pipe,
color) and stored in packet mbuf.
set dpdk interface hqos pktfield <interface> id subport|pipe|tc offset
<n> mask <hex-mask>
